Bo it known that 1, Benton ULAIHl Vi m'rn a citizen of the United Stains, l'orinorly residing at Mos rove, Pmuisylvnnia, but now r0 siding at Chicago, in tho county of Cook and State of Illinois, have invrotod or disoovorod certain now and useful improvements in Manuiarturo of Glass Plans, of which i1nprovemonts the fol lowing is a spwilioation.

in Letters l-atont No. 805.610, grai'ltod to me Novtrmlwr Hl lfi, I have described and claimed on llillil'l Vtlili-llli in tho nianufmituro of glass plains n-hirh rimsistvd, gonornlly stated, in forminga potlore of shoot and then forming: tho omaining portion on tho portii'm first fornovd. in tho spooiih? ms'thod and ap laraitus disclosed in snid patent the portion rst formed reduced to shag-1o and thinkness approximately and then distrihutod along or deposilvd on a hell or rahlo, and the remaining portion of glass is rodnood to shape and a iiproximato ttioknoss and distributed along or dopositvd on tho portion first formed Tho inv'ontion dvsorihnd heroin rolatos to unrtiiinadditional or inrtlior improvomsnts in that method bro-idly rlain'iod in said pal-- ant; and it consists. z onsrally stated. in spreading a portion ot a n aas oi.

in tho )raotioo ol my invention It! proper spacing oi the spreorlingwolls 1 non 5 rolativo to the table can be accomplished in many ways. A desirable construction for that purpose consists in snouring to or lorlnin on the table. two linos of rails 4 and 5, the rai s 5 r0- jorting a greater hoight from the surface 0 the table than the rails 4. VVhilo not essential, it is preferred that the rolls should be made of the same or up iroximatol the same length and that the rails 5 shoul have their supporting-surfaoos above and as nearly as practicable in line with the corresponding surfaces of the rails 4, so as to permit of the utilization of a maximum amount of the surface of the table for forming purposes. In order to permit of the roll 1 resting on the rails 4, grooves 6 are out in the roll for the reception of the rail 5, as clearly shown 1n Figs. 4 and 5. The distance the rails project above the surface of the table determines the thickness of the portion of the sheet first formed, while the thickness of the portion of the sheet formed on the first portion is determined by the height of the surface of rail 5 above the bed or table. v

Where a side delivery of the finished plate is desired, the roll supporting and spaoln rails are omitted, and the rolls are provided with collars 25, which are loosely mounted in grooves in the rolls. These collars roll along the table, and by pro orly proportioning the thirknesses of the co ars the proper spacin of the rolls relative to the table is attaine As the collars are loose on the rolls, the latter can slip therein, thus avoiding a rubblng movemont of too rolls on the glass.

in forming plates, as I prefer to term the ('filllplfltefll article, a suflioient quantity of to produce the two portions of the shoot vomposing the finished plate is oured onto the table in front of the roll 1, w iich is than caused to roll forward along the table and spread a portion of the glass over the surlaco of the table. After the first portion of the shoot is Formed, the roll 2 is brought into operation moving along the table in a direction the reverse of the operative movedesired to incorporate a metallic wol) in the plate formed as described, it is placed on the portion of hht'filluht formed lm-wurd or oprrw tivo nu-venu-nt ol' the roll 1 and before said roll is returned to its initial position, so that such eturn movement may be utilized to embed the fabric or wire rncsh in the first-- formed portion of the sheet, and thus providing ll. sinooth surface on which to spread the remaining portion of the gloss.

While the rolls l and 2 may be caused to traverse the table successivel and independently of each other, it is preicrrcd that they should be coupled together so as to troveroo the table simultsrneously in both directions. The rolls can he coupled by any suitable means has, for exnropir, 11;, the lnrls ii, having collars 7, lit ng loosely over the trimnions t on tho endo of the rolls. us Sllfi'jlv'l in Figs. 1 and 2. When the rolls are thus con pled, the glass is poured onto the table 11+ tween the rolls, which are then caused to move forward and hook over the table, or the latter is given a, similar mo ement under the rolls. During: the for-v. gird movement of the rolls or table one of the former will not to r rend .1 portion of the glass on the table, and wiring; the backward movement the otlurr roll will not to spread the remaining pul'tioi'; of the glass over the surface of the portion first spread.

Any suitable means may be cmplo'red for causing the forward and return movements of the rollsan.wh for example, as thut shown in Fl s.1 and The rolls 1 and 1': are provide at their ends with sprocket wheels 10, having their piteh-dishoote s equal to the diameters of the rolls, and s rocketewheels 11 and 12 are secured to s alts 13 and 14, mounted in suitable hun ings at the respective ends of the tehio. Chains 15, having one and secured to anchors 16 at one of the tables, pass over the srhoeln wheels on one of the rolls, iilttili over the s ocket-wheels at the end of the table where t e chains are anchored, forward over the sprocket-wheels at the opposite end of the table, back around the sprocket-wheels on roll 2, and then. forward to anchors 1?, While power may he applied to one of the rolls or to the shaft, it can he rnoro convertiently applied to the shnit, as As thin shaft is rotated thcrolls are shnilorly rc-tuted by the chains and. roused to roll toward the shaft 13 When the shaft is rotated in the opposite direction, the rotation oi the rolls is reversed, and they wiil roll toward the U'P'PEJV- site end of the table.

While not necessary, it is preferred to prw vide it support. for the metal fabric which is to be incorporated in the plate. Such su port is conveniently formed by extending t 1e coupling-burs 6 and. connetilv such extensions by a cross-bar 18, to whic is secured s fabric-supporting plate 19, arranged in. a
